过了之后感觉曾经真的做过这样的类型的题. 之前一直非常疑惑二级排序的优先级问题,如今发现二级排序真的没有绝对的优先级. 对于此题,若按W排序,则有1到i件物品的W均小于等于第i+1件物品(设为A)的W,那么对于第i+1件我们在[1,i]中要选取一个B,使得B.w < A.w && B.h < A.h 且B.h尽可能的大. 这就是所谓的最接近A的B. 由于对于W,后面的均大于等于前面的,所以我们须要一个尽可能大的H. Splay_Tree实现. #include <algo…

题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=1677 题意: 玩俄罗斯套娃,问最后至少还剩几个. 题解: 这题可以和拦截导弹做对比,因为这里是二维的,按w递减h递增的方式来保证在保存的序列中按h升序来排的,从而为二分查找打下基础. 否则,如果按h降序排,保存的序列就会无序,二分结果自然不正确了. #include<iostream> #include<cstdio> #include<algorithm> using…

Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Given the list [[1,1],2,[1,1]], By calling next repeatedly until hasN…
